A. Molecules from solution of higher concentration to low concentration B. Molecules from solution of low concentration to high concentration C. Water from solution of high concentration to low concentration D. Water across a semi-permeable membrane from solution of low concentration to high concentration E. Water across a semi-permeable membrane from solution of high concentration to low concentration
Correct Answer: E
Explanation
Osmosis is a special case of diffusion in which only water molecules move from a region of high concentration to one where they are in low concentration through a semi-permeable membrane.
